Question about Hoover Fusion Plus Cyclonic Upright Vacuum Vacuum

3 Answers

High pitch My Hoover fusion vacuum cleaner began making a high pitch sound that makes it very annoying to vacuum. I cleaned all the things I could clean. I even cut out all the hair that was entangled in the brushes. Any idea what is causing the sound. It sounds like an siren is going off.

Re: high pitch

The Hoover Fusion has design flaws in the motor, including a metal plate that is too thin to contain the forces acting on the motor, particularly the constant strong tension from the drive belt, and a plastic plate that is attached to the metal plate by two screws that gradually loosen over time. Assuming the filters and canister are clean, a high-pitched noise coming from the motor indicates it is about to fail as a result of these problems. You can replace the motor after it fails, but the problem will eventually occur again. For those very mechanically inclined, when the motor first starts making the high-pitched noise, you can dismantle it and tighten all screws.

Re: high pitch

There are two filters, both are accessed after you remove the container. One is at the top, simply unlatch and clean or replace.And one at the bottom, which is supposed to filter the incoming air for the motor. If you remove those filters and turn on the power and the sound remains, it's not likely the filters however. Fine dirt and even large particles can get inside the fan motor and create a problem, causing greater vibration and a high pitch noise like it wants to explode. The motor needs to be opened and cleaned thoroughly or replaced by a repairman. The cost may not be worth it.

Re: high pitch

Sounds like you have a clog. Make sure the filters are clean, replace if it has been more then a year, check the inlet down by the brush roll, your clog maybe there.

High pitched sound when power on

I had a vacuum cleaner that did the same thing. My vacuum had three suction levels. The noise level would decrease as I lowered the level. I also noticed that when I turned the vacuum off the sound didn't stop instantly, it wound down/faded off as the motor slowed down. I found the problem to be the bearings in the main motor. I've been told that the motor that powers the carpet brushes can also make the sound if the motor bearing fails.

High pitched sound is often caused by air leaks in air ducts. This will also cause hoover loosing sucking power and slightly overheating.

If the hoover is overheating a lot, then noise can also come from the motor. In that case the part must be rplaced.

Try replacing the cone filter, the secondary filter, and the insulation at the top of the machine.
If that does not fix the problem, then the hoover must be taken apart to clean or repair the air duct.

Loud rattling noise.

Hi there SmartAlec from here. Often when an upright is making a rattling noise it can be something caught in the roller and every time the brush turns it knocks against the body and since it turns really fast it can sound quite bad. Take the roller out and clean inside that area and see if that helps. Hope it does. Happy Vacuuming :)

High pitched noise

It sounds like you may have a bearing problem. The motor bearing eventually gets damaged by the water vapor that is drawn in by the fan. This will cause a high pitch squeel from the motor. It is possible to replace the bearing, but it should be addressed by a professional techician.
